  • Rated 5 out of 5 by from Very good looking and substantial I purchased this dead bolt lock to accompany a Kwikset outdoor handle set. The black iron has a clean modern look on my new front door. The mechanism is smooth and secure. I am a somewhat handy female, who found the installation simple and quick.

    Rated 5 out of 5 by from Great customer service! I bought a Deadbolt from Kwikset online from a large eCommerce retailer. It was several weeks before the carpenter got around to installing in. The bolt was missing from the box. I called Kwikset and they were very helpful and mailed out a replacement in a very timely manner. I also like the feeling of security the product provides as it seems very clear that if for any reason I forget my keys, I am NOT getting in. Thank you Kwikset for the great service.

    Asked by: ptushi
    Hello ptushi, We have changed the orientation of the turn piece. The turnpiece is vertical when locked, and horizontal when unlocked. Sincerely, Kwikset Support Team
